"When you open the app, you will realize the feed is loaded immediately," Reddit engineer Chen Chen said. "Even when the network is slow, it still feels very smooth."

Reddit CEO and co-founder Steve Huffman said, "The app is already the fastest way to browse Reddit, and it will serve as the foundation for many updates to come."

Reddit claims the jump to mobile isn't a rush to increase revenue, but that it's about improving user experience over the long haul.

Huffman told users during an "Ask Me Anything" session in July: "Reddit has a lot of cash. Monetization isn't a short-term concern of ours. ... We will continue to experiment with different efforts so that when (the) time is right we know what works and what does not."
